If a twin system is used (see Par. 6.3) on page 8.0 you can set
Page 8.0
one of the 3 possible twin operation modes:
Alternate every 24h: The 2 circulators alternate in reg-
ulation every 24 operating hours. If one of the 2 mal-
functions, the other takes over regulation.
Simultaneous: The 2 circulators work at the same time
and at the same speed. This mode is useful when a
flow rate is required that cannot be provided by a single
pump.
Main/Reserve: Regulation is always performed by the
same circulator (Main), the other (Reserve) takes over
only if there is a malfunction of the Main one.
If the twin communication cable is disconnected the systems
automatically figure as Single, working completely independent
of each other.
On page 9.0 it is possible to choose the parameter to be dis-

H: Measured head expressed in metres
Q: Estimated flow rate expressed in m3/h
S: Rotation speed expressed in revs per minute (rpm)
E: Head requested by external signal 0-10V or PWM, if active
P: Power distributed expressed in kW
h: Operating hours
T: Liquid temperature measured with the sensor fitted on board
T1: Liquid temperature measured with an external sensor

On page 10.0 you can choose the language in which to display
the messages.

On page 11.0 you can display the alarms log by pressing the
right button.
If the system finds any faults it records them permanently in the
Alarms Log
alarms log (up to a maximum of 15 alarms). For each recorded
alarm a page composed of 3 parts is displayed: an alphanumer-
ic code that identifies the type of fault, a symbol that illustrates
the fault in graphic mode, and a message in the language se-
lected on Page 10.0, giving a brief description of the fault.
By pressing the right button you can scroll through all the pages
of the log.
2 questions appear at the end of the log:
"Reset Alarms?"
Pressing OK (left button) resets any alarms still present in the
system.
"Delete Alarms Log?"
Pressing OK (left button) deletes the alarms memorised in the
log.
On page 12.0 you can set the system status in ON, OFF or
Pagina 12.0
controlled by a remote signal EXT (digital input IN1).
If ON is selected the pump is always on.
If OFF is selected the pump is always off.
If EXT is selected, reading of the status of digital input IN1 is
enabled. When input IN1 is energised the system goes ON and
the pump is started (on the Home Page the messages "EXT"
and "ON" appear alternately at bottom right); when input IN1 is
not energised the system goes OFF and the pump goes off (on
the Home Page the messages "EXT" and "OFF" appear alter-
nately at bottom right).
For the connection of the inputs see par. 6.2.1
